The patient has new-onset restlessness and confusion. Pulse rate is elevated, as is respiratory rate. Oxygen saturation is 94%
The nurse ignores the pulse oximeter reading and calls the health care provider for orders because the pulse oximetry reading is inaccurate. Which factors can cause inaccurate pulse oximetry readings? (Select all that apply.)
a. O2 saturations (SaO2) > 70%
b. Carbon monoxide inhalation
c. Hypothermic fingers
d. Intravascular dyes
e. Nail polish
f. Jaundice
ANS: B, C, D, E, F
Inaccurate pulse oximetry readings can be caused by outside light sources, carbon monoxide (caused by smoke inhalation or poisoning), patient motion, jaundice, intravascular dyes (methylene blue), nail polish, artificial nails, metal studs, or dark skin. SpO2 is a reliable estimate of SaO2 when the SaO2 is over 70%.
